Rhabdomyolysis is a syndrome caused by injury to skeletal muscle, which results in leakage of large quantities of potentially toxic intracellular contents into plasma. Causes include direct trauma, drug use, genetic muscle diseases, hyperthermia, seizures, ischemia, and severe exertion. We describe a rare case of exercise related rhabdomyolysis of the abdominal wall in a 23-year-old football player. He presented with painless hematuria after starting a new abdominal workout routine to lose weight. Although the workout was not excessively strenuous, it involved new exercises targeting a poorly trained muscle group. Results of initial workup indicated severely elevated levels of creatine kinase. Furthermore, an abdominal computed tomography scan revealed intrafascial and intramuscular edema in and around both external oblique muscles. The patient required no hospitalization and was successfully treated with oral hydration, with recommended close follow-up.
